personal injury.
HOW TO AVOID THE HAZARD
Keep fingers, hands, and clothing clear of rotating
components and hot surfaces.
CAUTION
POTENTIAL HAZARD
Raising the tractor frame for service or maintenance
relying solely on mechanical or hydraulic jacks could
be dangerous.
WHAT CAN HAPPEN
The mechanical or hydraulic jacks may not be enough
support or may malfunction allowing the unit to fall,

for support. Use adequate jack stands or equivalent
support.
